Estimating the population density of Mongolian gazelles Procapra gutturosa by driving long-distance transects
نویسندگان
چکیده
varied from 10.7 gazelles km−2 in spring to 11.5 gazelles km−2 in autumn, with total population estimates of 803,820 (483,790–1,330,100 95% confidence interval) and 870,625 (499,432–1,491,278 95% confidence interval), respectively. Confidence limits were wide, and to obtain a coefficient of variation of 20%, transect lengths would need to be extended threeto four-fold. Until more efficient means for conducting population surveys can be implemented, driving long-distance transects, combined with distance analysis, seem to provide the best quantitative estimate of Mongolian gazelle populations.

A mega-herd of more than 200,000 Mongolian gazelles Procapra gutturosa: a consequence of habitat quality
In September 2007 unusual precipitation patterns created conditions in the eastern steppe of Mongolia (drought conditions in many places and wet conditions in one area) that led to the observation of a historically large Mongolian gazelle Procapra gutturosa herd (. 200,000). A model developed to predict gazelle occurrence based on satellite imagery of vegetation productivity correctly identifie...
متن کاملManagement and Conservation Note One-Sided Barrier Impact of an International Railroad on Mongolian Gazelles
We conducted a carcass census of Mongolian gazelles (Procapra gutturosa) along the Trans-Mongolian railroad in June 2005. We counted 241 gazelles that had died within the previous 12 months. Carcass numbers were greater on the southwestern side in the northern 3 zones, but we found carcasses only on the northeastern side in the southernmost zone. It suggests that impact of the railroad was stro...
متن کاملIsolation and Characterization of Cross-Amplification Microsatellite Panels for Species of Procapra (Bovidae; Antilopinae)
The three Procapra species, Tibetan gazelle (P. picticaudata), Mongolian gazelle (P. gutturosa) and Przewalski's gazelle (P. przewalskii) are endemic to Asia. Several intraspecific genetic issues have been studied with species-specific microsatellite loci in these Asian gazelles. However, cross-species microsatellite panels are absent, which inhibits comparative conservation and evolutionary st...
متن کاملFragmentation of the Habitat of Wild Ungulates by Anthropogenic Barriers in Mongolia
Habitat loss and habitat fragmentation caused by anthropogenic activities are the main factors that constrain long-distance movement of ungulates. Mongolian gazelles (Procapra gutturosa) and Asiatic wild asses (Equus hemionus) in Mongolia are facing habitat fragmentation and loss. To better understand how their movements respond to potential anthropogenic and natural barriers, we tracked 24 Mon...
متن کاملNiche divergence accelerates evolution in Asian endemic Procapra gazelles
Ecological niche divergence and adaptation to new environments are thought to play important roles in driving speciation. Whether recently evolved species show evidence for niche divergence or conservation is vital towards understanding the role of ecology in the process of speciation. The genus Procapra is an ancient, monophyletic lineage endemic to Asia that contains three extant species (P. ...
